TO ALL WHOM IT MAY CONCERN:

Be it known that I, DAVID YOUNG, 5f East Topsham, in the county of Orange, and State of Vermont, haveinvented a new and improved Sugar-Pan Derrick and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, referelice being had to theaecompanying drawingsyforiniug part of this speoilioationQ-jin which- Figure 1 is a side view of my improved derrick,with a removed section showing the tongue.

Figure 2 is a horizontal section of the same, through the line a: x, fig.

Similar letters of reference indicate corresponding parts.

This invention relates to the moving of sugar-pans from the arches on which the same are placedfor evaporating the sap or cane-juice. i V

It consists of a derrick formed of an upright, A, and two horizontal beams, B, braced with brackets, D, in the usual manner, in combination with the other devices perfecting the whole, for the purpose required, which will hereinafter be more fully set forth.

The block E is made with its two lower corners or edges recessed, to form a tongue, as shown, which fits between the beams B 13,50 that the said block may rest securely thereon without being aflixed thereto,

Through a mortise in the block E the vertical stail G fits with easy cbnt'ac't, and is movable up or down, To the lower end of the said staff is ailixed a frame, shaped like the letter H, it being simply a cross-piece, a,

(the lengthof which is or approximates-to the width of .the common sugar-pans,) and parallel pieces, 6 b,'(tho 'at will.

length is or approximates to the length of common sdgar-pansn) mortised or otherwise afiixed firmly together, as shown. i I

At each'end of the pieces 6, two hooked rods or links, ii, are loosely attached forthe purpose of' hooking intocorrespondiugloops, rings, or links, 0, at the corners of the sugar-pans M, as they rest unon the arch or arches N." m A cord, rope, or chain, I, passes from the Windlass it over the pulleyJ inithebearns-B, and the pulley e in the block E, and thence down through a hole or channel in the block to the frame at tho'bo'ttom o f the stafi, where-it is afiixed to the said frame by a shackle r0dand pin, as shown, or in any other suitable menner.- By this device the pans maybe raised from the arches, and sw-ungaway from the same in the manner common to derricks. I

The black E slides along on the beams B wh enmade to 'do ,so by; pushing or pulling the stafl G, whereby.

the frame and hooks can thus be brought over each of the several pans on the arches successively,'hut when not so pushed or pulled, the friction of the blocl: upon the beams is generally sufiicicntsto holdit again-st tend ency to move along, on the beanisfwhicli may be occasioned by the cord I, but if not, holes may be made lat,

erally through the beams, B, and a similar hole in the-block E, for the recc'otion of a key or pin to hold the block securely. v I

By the crank-handle D the cord is wound or unwoundon the windlass'h, and the pan M raised or lowered The upright, A, swings on the post F, by eye-and-piutle hinges, as shown, audio, rod oi-peg, P, passes through a hole in the upright, A, 'and also in the post. F, to hold the derrick in s'fixed position over the sugar-pans i'n thearches This peg is withdrawn when the pans are to be swung olf after being lii't cd cleah of the arches. Iron pins 2., radiating fro n'the Windlass 7i, serve, in connection with'a removable pi u, j, tohold the windlass from unwindingund lowering the pan at any point of its suspension. Thepin ,7 may be attached by acordto the upright A, or other conileuient point.

The stafi G steadies the path; when lifted and swung oil, so that the sirup may not be spilled. The block 7 E enables the staff and frame to be brought over the difi'er'ent pans on the arches.

My improved de'rricks can be cheaply constructed of wood, and supplies awant long'felt in theuianufacture of maple and sorghum-sugar,'whcre the pans heretofore'were lifted-fromthe arches by hand;

I claim as new, and desire to secure by'Letters Pateut- 1. The steadying -etafi G and frame a b 15, substantially as shown and described, in combination with the cord I and derrick A B D,- all as and for the purpose set forth. i

2. The block E, bearing the pulley e, and held between the arms B of the derrick, when said block is slotted for the passage of the vertical bar G, which steadies the pan asjt is elevated by the cord I, as herein shown and described.

3. The arrangement of the steadying bar. G, frame q 6 b, pulley e, slotted block E, arms B, and elevatingcord I, with relation to the derrick A D, whereby a series of pans in crew is elevated in a vertical line without removing the derrick, as herein shown and described.

DAVID YOUNG.
